On February 11, 2018, I upgraded to premium. Shortly thereafter, I upgraded my Mac to High Sierra. After problems entering my password and finally getting access, I no longer have the premium version and the wrong mobile device is entered in my account. Please advise.

Hi, I attempted to pay using paypal, but Paypal couldn't process the payment because my credit card flagged the transaction as suspicious. If I attempt to purchase a subscription again I receive the message, "An active recurring subscription exists. No need to buy again." Can someone help me complete this purchase?
